Bisgoeppertia is a genus of herbaceous, short-lived twiners, endemic to the Greater Antilles (Cuba and Hispaniola). It consists of three well characterised species: B. gracilis on serpentinite soils in the western half of Cuba, B. robustior also on similar substrates in eastern Cuba and B. scandens limited to the Dominican Republic in Hispaniola. In spite of being the most often collected of the three, B. robustior so far lacked a legitimate name, having been confused with either of the two others; it is described as a new species.
